Claims. (Cl. 229-15) My invention relates to cartons that are particularly suitable for the carrying of beverage bottles, and especially to those of the folding carton type.

One object of my invention is to provide a carton of the character referred to which consists mainly of two compartments each formed mainly from a single sheet of cardboard divided into panel-like areas and bent to form a side wall and one-half of top and bottom walls, together with end walls connecting the two compartments.

Another object of my invention is to provide a carton of the character referred to wherein each compartment mentioned above has an inner wall that is releasably hooked upon the upper edge of a partition at the vertical mid plane of the carton, where the two compartments meet, whereby when the inner walls are unhooked from the partition and withdrawn from between the end walls, and the lid-like panels raised, the carton can be collapsed by flattening the side walls against the end walls at the four corners of the carton.

In the accompanying drawings,

Figure 1 is a plan view showing one of the two blanks that form the top, bottom and side walls of the compartment;

Fig. 2 is a blank from which a partition wall of folded form is shown;

Fig. 3 shows one of the two blanks used in forming the end walls;

Fig. 4 is an edge elevational view of the blank of Fig. 3 bent to the shape occupied when in assembled position with the blanks of Figs. 1 and 2;

Fig. 5 is a sectional view of the blank of Fig. 2 bent to approximately its final form;

Fig. 6 is a schematic view showing the manner in which the blanks of Figs. 1 and 5 interengage with one another when shaped to final form;

Fig. 7 is a perspective view of the completed carton with parts broken away;

Fig. 8 is a schematic plan view showing the manner in which the side and end walls are collapsed for folding; and

Fig. 9 shows a separator for use in the container when bottles are to be carried.

Figure 1 is one of two blanks, each of which forms one of the two compartments in the box. That is, it forms substantially all of one of the two compartments (Figs. 6 and 7). The blank is folded so that its panel 10 forms one side wall; its panel 11 forms the bottom wall of one compartment, and the panel 12 serves as a hanger flap at the inner wall of the compartment, its upper edge being turned down at 13 to form a hook that will engage with a partition as hereinafter explained, to support the inner edge of the panel 11. The panel 14 constitutes the top wall of the compartment and has a down-turned lip 15 that hooks into the space between lips 13 of the two atnt compartments. The end flaps or wings 16 of the blank are folded against the inner face of the end wall herein after described, and stapled or glued thereto.

The blank shown in Fig. 2 serves as two partition walls 18 that are folded along the dash line as shown in Figs. 5 and 6. The four flaps or extensions 19 are bent at right angles and secured by gluing or stapling to the end walls as hereinafter explained. The edges 20 are engaged by the folds at 13 in Fig. 7. Half hand holes 21 are provided in the flaps 19 (Figs. 2 and 5).

In Fig. 3, one of the two end walls is shown. In this case, the main end panel 24 has a hand hole 25 and flaps 26 and 27, the flap 26 being folded downwardly at 26a over the upper edge of the two adjacent laterally-turned flaps 19 and is secured thereto. This flap 26 has a hand hole 28 matching the half holes 21, and a vertical slot 29 that receives the upper portions of the two partition members 18 of Fig. 4. At its lower edge, the flap is inturned upwardly and has a slot 30 that received the lower edge or fold of the partition 18 of Fig. 5.

In order to fold or collapse the box, the lids 14 are raised to disengage the hooks 15, and the bottom panels 11, together with their extensions 12, are pulled out of the box. Upon flattening the members 11, 12, 13, 14 and 15 to the planes of their respective side wall panels 10, the box can be bent along its four vertical corners to the collapsed condition shown schematically in Fig. 8.

Suitable cardboard separators 32 of the type shown in Fig. 8 will be usable in the compartments. These may be of the well known collapsible type used in egg crates.

I claim as my invention:

1. A foldable carton comprising a pair of oppositelypositioned members each of which is creased to form foldable panel-like areas that respectively serve as a side wall, one-half of a bottom wall, one-half of a top wall for the carton and an inner vertical flap, end walls for the carton flexibly secured to the said side Walls, a partition flexibly connected to the end walls at their vertical median lines, and a lip on the free edge of each flap, bent for hooked engagement with the upper edge of the partition.

2. A carton as recited inv claim 1, wherein each top wall panel has a downturned lip at its free edge that is frictionally engageable with the partition when the top walls are in closed position.

' 3. A carton as recited in claim 2, wherein the partition is in the form of two layers between the upper edges of which the lips of both the flaps and the top wall are insertible.

4. A foldable carton comprising a pair of oppositelypositioned members each of which is creased to form foldable panel-like areas that respectively serve as a side wall, one-half of a bottom wall and an inner flap, end walls for the carton flexibly secured to the said side walls, a partition flexibly connected to the end walls at their vertical median lines, and a lip on the free edge of each flap and bent into releasably hooked engagement with the is in the form of two layers between the upper edges of which the lip of each flap is insertible.
